Sliding type switch assembly

Abstract

A sliding type switch includes a non-conductive slide slidably engaged in a non-conductive housing and includes a knob extended outward of the housing for moving the slide. A non-conductive board is secured in the housing and three pairs of conductive prongs are secured to the board. The slide includes two openings for receiving two spring elements. The spring elements may be either conductive or non-conductive. Each of the spring elements engages a conductor and moves in concert therewith. The spring elements are provided with S-shaped springs each having two curved tips to bias the conductors to engage electrically with two pairs of the three pairs of conductive prongs.

I claim: 
     
       1. A sliding type switch comprising: a non-conductive housing enclosing a chamber and including an upper portion and a lower portion, with a slot formed in the lower portion;   a non-conductive board in the chamber and secured to the upper portion;   at least three conductive prongs secured to the board with the bottom of each of the prongs forming a conductive shoe;   a non-conductive slide member in the chamber and defining an elongated trough, the slide member connected to a knob movable slidably in the slot for selectively positioning the slide member within the chamber;   the conductive shoes aligned along the trough;   a spring element in the trough and having two projecting legs engaging with the slide member;   a conductor mounted on the spring element for conjoined movement therewith so as to engage electrically with two of the three conductive shoes;   an S-shaped spring mounted between the spring element and the conductor, the s-shaped spring having two ends each provided With a curved tip for biasing the conductor to engage with said conductive shoes.
